CONSTRUCTION OF DOME STIC STOVE-ZS AND GRATES.

SPECIFICATIQN forming part of Letters Patent No. 308,290, dated November18, 1884-.

Application filed May 20, 1884. (No model.) Patented in England February14, 1883, X0. 812, and January 1, 1fi8i. No. 1 14,

To all whom it may concern.-

Be it known that I, HENRY TnoMPsoN, of London, England, builder, haveinvented certain new and useful Improvements in the Construction ofDomestic Stoves and Grates, of which the following is a specification,reference being had to the accompanying drawings.

My said invention relates to improvements in the construction ofdomestic stoves and grates, whereby the coal or other fuel is suppliedto the fire from a'chamber at the back of the grate, the amount of smokeescaping up the chimney is greatly diminished, while at the same time aconsiderable economy in. the consumption of fuel, as compared withstoves and grates of ordinaryconstruction, is effect ed. The fire in theimproved stove or grate is similar in appearance to the fire in anordinary open stove or grate. The front bars, the bottom, and the sidesof the stove orgrate are constructed and arranged in the ordinarymanner, and the back, which consists of a metal plate, instead of beingfixed as in ordinary stoves, is pivoted at the bottom, and is soarranged as to be capable of revolving back ward from its normal uprightposition into a more or less horizontal position. The said back of thestove or grateis prolonged at the bottom below its pivots, suchprolongation acting as a weight to counterbalance that portion of theback which is situated above the said pivots, and by so doing tends tomaintain the back in an upright position. The said back turns on itspivots within a chamber at the back of the stove, and when in an uprightposition forms the front side of such chamber, while when in a more orless horizontal position it forms the bottom of the same. The upper partof the said chamber is formed by the prolongation of the back there of,which is arranged to extend between the chamber and the lower part ofthe chimney, and in order to allow of the supply of fuel to the chamberthe extremity of the said project-ing portion is arranged to turn onpivots, so that when such hinged portion is turned back a channel ispresented, through which the fresh fuel can be supplied to the chamber,the back of the stove or grate having been brought for that purpose intoa more or less horizontal position, ashereinbefore described.

The chamber having been supplied with the desired quantity of fuel, thesaid hinged projecting portion is returned to its normal position.

In order to allow of the proper combustion of the gases and smokeevolved by the fuel contained within the chamber at the back of thestove or grate, the lower face of the hinged upper portion of the backof the chamber is perforated, such perforations serving to conduct thegases and. smoke to perforations leading to a channel or channels whichpasses or pass at the rear of the chamber and opens or open at a pointbelow the fire-bars. (In some cases the whole of the back of the chamberis perforated for effecting the same object.) The gases and smoke willthen be drawn into the fire and there consumed. The space between thefront of the fire-bars and the hearth is in some cases more or lessclosed by a plate, which may be provided with apertures for regulatingthe admission of air.

In some cases a bar is arranged to project below the end of the hingedportion of the up per part of the back of the said chamber, so

between the upper surface of the fuel and the extremity of the saidhinged portion of the back of the chimney.

I W-lll now proceed to refer to the accompanying drawings, from whichthe nature of my said invention will be more clearly understood.

Figure 1 is a front elevation of a stove constructed as hereinbeforedescribed, and Fig. 2 is a vertical section through the center of thesame.

The same letters of reference indicate like parts in both the figures.

A is the front of the stove.

B are the front bars. 0 is the bottom. The back of the stove is shown atl), and is pivoted at d.

Dis the weighted prolongation of the back.

E is the back of the chamber E, and e is the hinged projecting portionof the same.

- In Fig. 2 the back of the stove is shown in a more or less horizontalposition, and the hinged projecting portion 0 of the back of the chamberE is shown openthat is to say, in the requisite position to permit ofthe said chamber being charged with fuel. The posii tions of these partsare, however, shown re- .as to assist in preventing the escape of smokelCO versed in dotted linesthat is to say, the projecting portion 0 isshown closed and the back D is shown in an upright positiona position itwould assume when all the fuel had been discharged from the chamber E.

F is the channel, through which the gases and smoke or a portion thereofpass from the chamber E to a point below the fire-bars, and G is thebefore-mentioned plate for closing or partially closing the front of thespace between thefire-bars and the hearth. The bar projecting below thehinged upper part of the back of the chamber E is shown at H.

The fuel having been supplied onto the more or lcss horizontal back D ofthe stove or grate, as hereinbefore described, is brought forward intothe fire in the body-of the grate or stove by the rising of the saidback as the fuel is consumed in the said stove or grate. such risingbeing facilitated bythe action of the weighted xprolongation D orothermeans.

I lay no claim to anything. shown in German- PatentlNo. 3,919,: of 1877;

What I claim is- 1. The combination and arrangement of the pivoted backD, chamber E, and the hinged or pivoted projecting portion 6 of the backof the said chamber, substantially as and for the purposeshereinbeforeset forth and described.

2. The combination and arrangement of the pivoted back D, chamber E, thehinged or pivoted projecting portion 6 of the back of the said chamber,and the bar H, substantially as and for the purposes hereinbefore setforth and described.

3. The channel F, formed at the'back of the fuel chamber, for conductingthe gases and smoke from the upper part of the chamber E to a pointbelow the fire-bars, substantially as and for the purposes hereinbeforeset forth and described.

4. The channel F, formed at the back of the fuelchamber, for conductingthe gases and smoke from the upper part of the chamber E tola pointbelow the fire-bars, the space between the front of the latter and thehearth being more or less closed by the plate G, substantially as andfor the. purposes herein before set forth and described.
